How to make an extension work for several app targets? - ios

I have an iOS App target, open to everyone for the public store, all fine.
And I have 2 extensions with it in the project, including the bundle identifier in their identifier of that iOS App target.
Now I duplicated the first App target, added some changes, etc for B2B & MDM usage, but I want to use the same extensions, without having to change their bundle identifiers each time I change the build target, and I don't want to duplicate them as well with different bundle identifiers as well, if that is avoidable.
Visual example:
Basically I want to avoid delivering the code of the second target to the users of the first target, because after all, it is the minority who needs those changes.
I tried it with App groups, but that doesn't seem to help in any way.
Is there a way to make the extensions work for both App targets?

There are these option to you:
1.
You can duplicate the extensions, provide id from your developer portal, or let Xcode add them itself, and change the target identifiers to your new target.
2.
The other way is, to change the extensions bundle ids on build actions of the scheme to your currently required ones.
This could look somewhat like this, if you want to use PlistBuddy:
/usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier fullBundleIdOfExtension" $PROJECT_DIR/Extension\ Directory/Info.plist
fullBundleIdOfExtension is something like com.company.application.extension
This way could cause errors sometimes on the build after a target switch, showing a dialog that the App could not be installed. This requires you to perform a clean build and rebuild.

How do I make an iOS app's Build Identifier dynamic?

I am working on some Swift code with my children. We would like to work from a shared codebase, so that we can each grab the code, then build and install the app onto our phones.
When I grab the source code my daughter wrote, I get the errors:
The app ID "com.example.OurApp" cannot be registered to your development team. Change your bundle identifier to a unique string to try again.
and:
Xcode couldn't find a provisioning profile matching 'com.example.OurApp'.
If I change the Bundle Identifier value in XCode to something globally unique, everything works. But I don't want to do that because then it is confusing what changes should be committed and/or shared.
The Bundle Identifier value seems to be statically attached to the project files, and those project files need to be checked into to source control, which means that we have to manually muck with that value before we can build and sign our app so that we can run it on our phone.
We each have a developer account that gives us the ability to sign an ipa with our certs, which allows us to install builds on our phone.
I think I want to make the Bundle Identifier dynamic based on the machine or user that is building it.
I think I want to type com.myfamily.$(SOME_ENV_VARIABLE).OurApp into the Bundle Identifier box in XCode, and then commit that file so that any of us can just grab the code, mess with the code, then install the signed ipa on our phone without changing any of the XCode project file values.
No matter what I type into the "Bundle Identifier" box in XCode, the resulting value in the plist within Build/Products/.../Info.plist is garbage. Even changing some .swift files causes this plist to change to some junk value.
How do I make it so that I can share an XCode project with my family such that we can each sign and run the app, without changing or git-ignoring any of the project files/plists?
We are using XCode 8.3.x and running iOS 10.

Xcode: sharing the same Bundle ID among multiple people

I'm developing an iOS app with a friend. We both enrolled for the Apple development program as a Single person (we don't have an organization).
We're using git and we'd like to be both able to build the app from our Mac, but I can't compile sinche the Bundle ID is already used by my friend. Is it even possible to be both able to work on the same project without being an organization? What we should do?
Thanks
The problem is that only one developer account can register the bundle ID. What Xcode is trying to do is register the bundle ID to your development account (as you can do manually at https://developer.apple.com). Since your friend already did this, you cannot do this as well.
What you can do is either change the value of your bundle ID to a development one (in the end, only one of you can release the app on the App Store) however, this is kind of messy since it'll change the .xcodeproj and can be a real conflict mess when using versioning (as I guess you are using).
Another option is to use .xcconfig files, and define the bundle ID dynamically in your project. This way you can change your config file locally and just don't push that change. What you do is:
Add a new file to your project. Select Other under iOS and then select Configuration Settings File. Save the file and call it Debug.xcconfig (or whatever you want).
Add the following row to the file: BUNDLE_ID = io.example.app.
Select your project in the Project Navigator and then select the project itself under PROJECT.
Select the Info tab and expand both Debug and Release. For both Debug and Release select the Debug option.
Now open your Info.plist file and change the value of Bundle Identifier (CFBundleIdentifier) to $(BUNDLE_ID).
Now you can change the bundle ID (and a shitload of other Xcode project properties) using the configuration file. You could add one for yourself and your friend as well, each with their own bundle ID.
One problem though when changing the BundleID is that services such as APNS won't work. Keep that in mind. If that is important that both should be able to test, then make sure to get an organisation account.
Hope this helped you a little bit!

xcode compile flags to create two apps

To what extent can I use compile flags. I want to use the same xcode project but compile two apps. The differences are:
The bundleID
The Provisioning Profile used
The URL that the code uses to access it's services
The app name (the test app has 'Test' appended to it)
As mentioned, you need two targets. Each target get it's own bundle id, Info.plist etc. Crucially, it can share source code between the two app targets, so you can create a lite and pro version of your app (not sure if that's what you are trying to do).
All you need to do is pass -DPROVERSION=1 (or whatever) to the compiler in order to do conditional compilation within a shared source file:
#if PROVERSION
// Show supadupa feature
#endif
This is done within the Build Settings of the pro app target.

What are the best practices for preparing an iOS demo app along with main app?

This question is about the App development/testing process. I've an app on the App Store (say ABC); now I added some features on a separate git code branch and want to show these to my teammates.
I can use TestFlight to install it on their iPhones, although that overwrites my original app on the phone.
I'm looking for the best way to get a new App, say ABC Demo, installed on their iPhones.
If you want the "new" version of the app to work alongside the old version on the same device then each app will have to have different Bundle Ids. You can achieve this by creating a new Target in Xcode
http://www.itexico.com/blog/bid/99497/iOS-Mobile-Development-Using-Xcode-Targets-to-Reuse-the-Code
two finger click the existing target and select Duplicate
Then under the new target change the Bundle Identifier to something different
Go to Targets in Xcode
Get Info on your project's target
Search for Product Name under Packaging. Change it to ABC Demo
Press Enter

Prevent an iOS app from being updated

I am doing some research to find out if an app developer can set up an app in a way that it can't be updated, at least in some circumstance.
Or in another way: what can be done by a developer in order to create on purpose issue during the update of its own app?
It sounds like what you actually want to do is create another Target in your project. This way, you can have multiple copies of your app on the same device. For example, you could have a dev target that is constantly moving and a release target that you don't want to override.
You can do this by selecting your project in the project navigator, right clicking on your app's target, and then selecting Duplicate. It will create a new target called YourAppName-copy. You can then select your target next to where you select the device/simulator to run on & select the new target. Run the new target & it will install the new target and leave your other one alone.
For an enterprise app, you could support your own app updating (and create a web service to check to see if the app needs to be updated -- or if the user's credentials are still valid, etc.).
For a public App Store app, this is not currently possible.
