I have localizable English and French. I want display Registered symbols as a part of word i.e "MyApp®". English part of localization file shows this symbol correct in iOS APP UI. Same needs to display for French version i.e "MyAppᴹᴰ" but space comes in between 'M' and 'D'.
I also tried using unicode like MyApp\u{1D39}\u{1D30}. This gets worked in Swift playground but if I try it through Localization file it doesn't work.
iOS version: 11.4
I need to make changes in localization file only and not to use NSAttributed string every where in code.
If anyone came across same problem, and found solution please post.
"MyApp®" = "MyApp\u{1D39}\u{1D30}" // Localization file
print(String(describing: "MyApp\u{1D39}\u{1D30}" // swift playground
print(String(describing: "ᴹᴰ")) // swift playground
"MyApp®" = "MyApp\u{1D39}\u{1D30}" // Localization file
"MyApp®" = "MyAppᴹᴰ" // Localization file- on UI space comes b/w ᴹ and ᴰ
print(String(describing: "MyApp\u{1D39}\u{1D30}")) // swift playground
print(String(describing: "ᴹᴰ")) // swift playground
"MyApp®" = "MyApp\u{1D39}\u{1D30}" // Localization file
On iOS app UI component should render MyApp® as MyAppᴹᴰ and no space between ᴹ and ᴰ.
Instead of using the separate superscript ᴹ and ᴰ characters, why not use the actual 🅫 (U+1F16B) character?
In your localization file, put:
"MyApp®" = "MyApp🅫"
I'm pretty new to Fastlane and love the idea of Snapshot, but I got a little problem.
When I'm trying to create a new set of screenshots I'm facing the problem that the UITests don't use the correct localized Strings to fetch the UI elements.
My current state is based on this Stack entries: XCode 7 UITests with localized UI
The localization method:
func localizedString(_ key: String) -> String {
let uiTestBundle = Bundle(for: MyUITests.self)
return NSLocalizedString(key, bundle: uiTestBundle, comment: "")
}
Trying to perform a tap that way:
app.navigationBars[localizedString("key_1")].buttons[localizedString("key_2")].tap()
The error I get is the following:
No matches found for "Rolling stone" NavigationBar
Rolling stone is the Base/English Localization of the key, but there should be a German one. So for any reason the UITest always picks the English Localization.
Does anybody have an idea how to troubleshoot this? I checked the SnapshotHelper and it passes a "de-DE" as the language, so that's not the point.
But I just can't find the Bug :(
Localization
This link here should be sufficient enough to solve your problem. You simple pick the correct language option during the test tab under edit scheme option.
I'm doing a .or query which in every platform works fine except in iOS.
As soon it reaches the line where it does the .or, it crashes with:
System.Collections.Generic.List> doesn't implement interface System.Collections.Generic.IEnumerable>
Assertion: should not be reached at mini-trampolines.c:183
Here's the code:
var isChallenger = ParseObject.GetQuery("Match")
.WhereEqualTo("Challenger",fb.loggedUser);
var isChallenged = ParseObject.GetQuery("Match")
.WhereEqualTo("Challenged",fb.loggedUser);
ParseQuery<ParseObject> query = isChallenger.Or (isChallenged); // Crashes here.
I'm doing it just like in the docs, not sure what's wrong.
Any help would be much appreciated!
Thanks,
Pablo
I think this is a bug I reported here: https://developers.facebook.com/bugs/750897958275392/
Except, I only saw this bug when using ParseQuery. The workaround I used is to use ParseQuery only, but I see you're already doing that. Is the code you posted exactly the same as the code you're actually using?
Is it just me or Xcode 6 (6.0.1) with Swift seems to be super slow when you type your code, especially with autocompletion?
A normal Objective-C class, even if inside a Swift project, works almost the same as before, so it's Swift that kills it.
Does anyone else experience the same inconvenience? Do you have any idea of how to improve performance?
I tried to play with some settings but no luck.
I've also of course tried restarting Xcode and the computer with no luck.
No other heavy
apps are open.
I use a Mid 2009 Macbook Pro (2.26 GHz Intel Core 2 Duo) with 8GB RAM and SSD HD, which is not the newest thing at all, but still not a complete junk.
It is a shame as I was excited to start using Swift and it is now really unbearable.
Thoughts / tips?
Quit Xcode and restart the Mac are not required but preferred.
Delete the content of the folder
~/Library/Developer/Xcode/DerivedData
Delete the content ~/Library/Caches/com.apple.dt.Xcode
This is a temporally solution, but works greatly.
Below the script using Script Editor app.
tell application "Terminal"
do script "rm -frd ~/Library/Developer/Xcode/DerivedData/*"
do script "rm -frd ~/Library/Caches/com.apple.dt.Xcode/*"
end tell
Alternatively, you can create an alias for your terminal like this:
alias xcodeclean="rm -frd ~/Library/Developer/Xcode/DerivedData/* && rm -frd ~/Library/Caches/com.apple.dt.Xcode/*"
You can add that to your ~/.bash_profile and then type xcodeclean on the command line every time you would like to clear those two folders.
I also experienced 100%+ CPU while typing some "simple" code. Some small tricks to make the swift-parser quicker by the way you structure your code.
Don't use the "+" concatinator in strings. For me this triggers the slowness very quickly.
Each new "+" brings the parser to a crawl, and it has to reparse the code everytime you add a new char somewhere in your function body.
Instead of:
var str = "This" + String(myArray.count) + " is " + String(someVar)
Use the template-syntax which seems much more efficient to parse in swift:
var str = "This \(myArray.count) is \(someVar)"
This way i basically notice no limit in strlen with inline vars "\(*)" .
If you have calculations, which use + / * - then split them into smaller parts.
Instead of:
var result = pi * 2 * radius
use:
var result = pi * 2
result *= radius
It might look less efficient, but the swift parser is much faster this way.
Some formulas won't compile, if they have to many operations, even if they are mathematically correct.
If you have some complex calculations then put it in a func. This way the parser can parse it once and does not have to reparse it everytime you change something in your function body.
Because if you have a calculation in your function body then somehow the swift parser checks it everytime if the types, syntax etc. are still correct. If a line changes above the calculation, then some vars inside your calculation / formula might have changed. If you put it in an external function then it will be validated once and swift is happy that it will be correct and does not reparse it constantly, which is causing the high CPU usage.
This way i got from 100% on each keypress to low CPU while typing.
For example this 3 lines put inline in your function body can bring the swiftparser to a crawl.
let fullPath = "\(NSHomeDirectory())/Library/Preferences/com.apple.spaces.plist"
let spacesData = NSDictionary(contentsOfFile: fullPath )! // as Dictionary<String, AnyObject>
let spaces : AnyObject = spacesData["SpacesDisplayConfiguration"]!["Management Data"]!!["Monitors"]!![0]["Spaces"]!!
println ( spaces )
but if i put it in a func and call it later , swiftparser is much quicker
// some crazy typecasting here to silence the parser
// Autodetect of Type from Plist is very rudimentary,
// so you have to teach swift your types
// i hope this will get improved in swift in future
// would be much easier if one had a xpath filter with
// spacesData.getxpath( "SpacesDisplayConfiguration/Management Data/Monitors/0/Spaces" ) as Array<*>
// and xcode could detect type from the plist automatically
// maybe somebody can show me a more efficient way to do it
// again to make it nice for the swift parser, many vars and small statements
func getSpacesDataFromPlist() -> Array<Dictionary<String, AnyObject>> {
let fullPath = "\(NSHomeDirectory())/Library/Preferences/com.apple.spaces.plist"
let spacesData = NSDictionary(contentsOfFile: fullPath )! as Dictionary<String, AnyObject>
let sdconfig = spacesData["SpacesDisplayConfiguration"] as Dictionary<String, AnyObject>
let mandata = sdconfig["Management Data"] as Dictionary<String, AnyObject>
let monitors = mandata["Monitors"] as Array<Dictionary<String, AnyObject>>
let monitor = monitors[0] as Dictionary<String, AnyObject>
let spaces = monitor["Spaces"] as Array<Dictionary<String, AnyObject>>
return spaces
}
func awakeFromNib() {
....
... typing here ...
let spaces = self.getSpacesDataFromPlist()
println( spaces)
}
Swift and XCode 6.1 is still very buggy, but if you follow these simple tricks, editing code becomes acceptable again. I prefer swift a lot, as it gets rid of .h files and uses much cleaner syntax. There is still many type-casting needed like "myVar as AnyObject" , but thats the smaller evil compared to complex objective-c project structure and syntax.
Also another experience, i tried the SpriteKit, which is fun to use, but its quite in-efficient if you don't need a constant repaint at 60fps. Using old CALayers is much better for the CPU if your "sprites" don't change that often. If you don't change the .contents of the layers then CPU is basically idle, but if you have a SpriteKit app running in background, then videoplayback in other apps might start to stutter due to the hardlimited 60fps update-loop.
Sometimes xcode shows odd errors while compiling, then it helps to go into menu "Product > Clean" and compile it again, seems to be a buggy implementation of the cache.
Another great way to improve parsing when xcode gets stuck with your code is mentioned in another stackoverflow post here. Basically you copy all contents from your .swift file into an external editor, and then function by function copy it back and see where your bottleneck is. This actually helped me to get xcode to a reasonable speed again, after my project went crazy with 100% CPU. while copying your code back, you can refactor it and try to keep your function-bodies short and functions/formulars/expressions simple (or split in several lines).
Autocomplete is broken since Xcode 4. Until Apple decides to fix this 2 years old bug, the only solution, unfortunately, is to turn code completion OFF on XCode's preferences (first option of the pic below).
You can continue to enjoy completion manually by typing CTRL space or ESC when you need it.
This is the only solution that works every time for 100% of the cases.
Another thing I have discovered recently is: if you use plugins on Xcode, don't. Remove them all. They make the problem worse.
Are you using Spotify?
I installed Yosemite GM with Xcode 6.1 GM on an iMac mid 2009 (2.66Ghz) having the same problem.I found that a process called "SpotifyWebHelper" is always marked red as not responding, so i disabled the option "start from web" in spotify and now Xcode seem to run significantly better.
I found out that usually happens when you:
have long expressions in a single statement (see this answer)
mix multiple custom operators in a single expression
The 2nd case seems to be fixed in one of the latest xcode releases. Example: I defined 2 custom operators <&&> and <||>, and used in an expression like a <&&> b <&&> c <||> d. Splitting to multiple lines solved the problem:
let r1 = a <&&> b
let r2 = r1 <&&> c
let r3 = r2 <||> d
I hope that your cases is covered by one of the 2 above... please post a comment either case
I had the same issues even in Xcode 6.3
super slow autocompletions
super slow indexing
enormous CPU usage by swift and SourceKitService
enormous Memory usage by SourceKitService
All this was happening even in relatively small project. I tried all the fixes I could find:
deleting ~/Library/Developer/Xcode/DerivedData/*
deleting ~/Library/Caches/com.apple.dt.Xcode/*
remove all "+" String combining from the code
removed all suspicious dictionary declarations
None of these actually helped in my project.
What actually solved my problem was:
placing each end every class in its own file
placing each and every extension in its own file (Class+ExtName.swift)
placing "out of class swift methods" in its own file
Now I have close to zero CPU usage, low memory usage, and decently fast completions.
Generally, moving the cache folder (DerivedData) to a SSD drive (specifically in my case - an outer storage connected to thunderbolt exit) has dramatically improved my Xcode performance.. Compilation time and general wondering around the app is about 10 time faster.. Also moved the whole git folder to the SSD, which dramatically improved git performance.
It was a pain until XCode 7.2.
Apple fixed it in XCode 7.3 and now it works like a charm. It's super fast and much more powerful as it seems to work a bit like the fuzzy search of files : you don't have to actually type the exact beginning of the method/property for it to appear in the list of propositions.
Collapsing all methods helps a little.
command-alt-shift-left arrow will do the trick...
To fold/unfold current methods or if structures use:
Fold: command-alt-left arrow
Unfold: command-alt-right arrow
SourceKitService is also kinda clumsy to deal with comments in the code and the embedded comments slow it down too.
so if you can afford to remove the massive blob of embedded comments like this:
/*
* comment
/*
* embedded comment
*/
*/
that can definitely help as well.
NOTE: in my case my Xcode 7.3.1 (7D1014) was literally blocked me typing any letter when the file had about 700 lines of comment with embedded comments. initially I removed that block from that .swift file and Xcode has become alive again. I tried added my comments back part by part by removing embedded comments, it was still slower than usual but it shown significantly better performance if there were no embedded comments.
I had the same issue where typing was lagging in a particular class and turns out that
/*
Long
multiline
comments
*/
was slowing down the typing.
I am trying to get the value "HELLO" of the UILabel shown in the iPad simulator.
I have enabled accessibility and have set the label as "Label Access".
But when I call target.logElementTree(), both the name and value are set to "LabelAccess" and as far as the apple docs say, the value field should contain the string that is set (in this case "Hello").
Does anybody know a fix for this?
PS: I am using the latest iOS SDK and Xcode.
Apple Stack Exchange
I think you encountered a UIAutomation bug that exists since forever.
Easiest way to get around this bug is to set the accessibilityValue to your text in code.
Something like this.
NSString *valueString = [NSString stringWithFormat:#"%d", value];
self.label.text = valueString;
self.label.accessibilityValue = valueString;
Helps those people that use Voice Over too ;-)
thanks for the workaround. Doesn't look like this bug has been fixed.
Came across this while writing Appium test for the iOS app. The element found by the driver somehow only contains accessibilityLabel and accessibilityIdentifier but not the actual text that's shown on the screen.
<XCUIElementTypeStaticText type="XCUIElementTypeStaticText" value=<accessibilityLabel> name=<accessibilityIdentifier> label=<accessibilityLabel> .../>
Has someone found if this issue has been logged with apple?
EDIT: Refer to this answer and the comment underneath. https://stackoverflow.com/a/11411803/4725937
Basically need to use [accessibilityValue]: https://developer.apple.com/documentation/uikit/uiaccessibilityelement/1619583-accessibilityvalue for accessible components for the display text to show up as XCUIElementTypeStaticText.value in the page source.
For eg:
someUILabel.accessibiityLabel = "This is used for voice-over"
someUILabel.accessibilityValue = "This is displayed text"
