I am working with an iOS mobile app written in Xamarin forms and distributed ad-hoc through Visual Studio App Center. My problem is that when an end user receives an email with the installation link, the app icon is extremely pixelated. The image used in the email is the 40x40 pixel version intended for notifications/iPad spotlight. I have tried to replace all the images in the project with new versions and made sure that all required icons were provided. However, it always uses the same image in the email.
How can I change the image that App Center uses as the project image?
In addition to posting this question here, I had reached out to the App Center technical team. I heard back from them with the following response:
For Android we will use the launcher icon size xxhdpi. For iOS, it is
using the CFBundleIcons.CFBundlePrimaryIcon or CFBundleIconFile. If
these are missing, we will use Icon#2x.png or Icon.png from your app
directory. The image update only happens when you release a new
binary. Once you distribute the binary to a a distribution group we
will retrieve the new image from your release and use that as the new
app image.
I have set the app for only iPhone but if I keep the images at Universal will it be used for iPhone
This is very much confusing please guide
Nope, You cannot do so. If you are targeting Universal Apps (iPhones + iPads) then App store need assets/images for both. Thus while uploading app to App Store it will show error saying "Missing assets".
I am trying to upload my app to TestFlight. I have created new provisioning profiles and have code signed the app as following:
In Xcode, the app successfully uploads to iTunes Connect, and soon after, I see the "processing build" screen on the Activity tab on iTunes Connect:
A few minutes later, the processing build disappears and there are no builds on the screen. I am unable to select a build as it simply says, Submit your builds using Xcode 6 or later, or Application Loader 3.0 or later.. How can I find the build on iTunes Connect? Thanks!
My solution... is terrible, but I have found success uploading builds until they show up. It sometimes takes like 30 uploads, and other times it only takes one. This problem is affecting every build I have tried since I switched to Xcode 8 in December. It's horribly inefficient but it's the only thing I have found that works.
EDIT: Right after I sent this answer, I got my build processed at upload 13. Good luck, buddy.
I also faced the same problem With xCode 9.
The reason behind it was, the new icon we have to include in App Icon for App Store (1024 * 1024) was in .jpg format instead of .png.
Here is the mail, I received from Apple.
Dear developer,
We have discovered one or more issues with your recent delivery for "MyAppName". To process your delivery, the following issues must be corrected:
Invalid Image - For iOS applications, icons included in the binary submission must be in the PNG format.
If your application supports the iPhone device family, you must include square icons of the following dimensions: 57x57 pixels.
If your application supports the iPad device family, you must include square icons of the following dimensions: 72x72 pixels.
For macOS applications, icons included in the binary submission must be in the ICNS format and must include a square 512x512#2x image.
Once these issues have been corrected, you can then redeliver the corrected binary.
Regards,
The App Store team
So my advice is
Look into your/client's mail box, you must have received email from Apple regarding the issue
Make sure you have included every image file in .png format
Make sure you have included every privacy description correct regarding the exact usage
For example, for Location usage description, instead of "App would like to use location", please write something like "Location is required for driver to find out where you are as well as for nearby suggestions."
Add missing items in info.plist, such as icon files, privacy usage description, requirements etc. It works for me.
AS iOS 9 is supporting App slicing feature just by adding needed images to image assets and you will get sliced app when download from appstore.
1) My question is do we need to do extra steps for App slicing feature or by just adding image to image assets it will work on Appstore (not like we are checking bitcode feature at the time of upload)
2) How can i deactivate App slicing feature even if i am using image assets.
1) No. You are right as per apple doc it clearly states here
2) I think we can not disable it.
Trying to answer your comment:
Theoretically:- i think if you some how forget to provide #....x image, still app store process will provide an alternative image to specific device. It may be same as #3x/#2x/#1x (what ever developer have provided ). If developer have provided more than 1 image like #1x and #3x both then #3x will be download to all device except #1x supported device.
Practically:-
Delete #1x or #2x what ever you want from image.xcasset.
Create archive.
Export the app for the target device to get ipa.
Change the .ipa extension to .zip and unpack the archive.
You should be able to see what images are there #1x/#2x/#3x. These
are the images which user will be downloading for his device.
I am bit confused on how to use the iTunes app icon when getting ready to distribute. I understand it has to be 512 x 512. But the part I don't get is it has to have no extension? I have extracted a couple apps and their iTunesArtwork is a unix executable. In the iTunes icon sample code from their website, for type, it just says Default data. How do I go about adding my iTunesArtwork to my project.
The 512x512 (or better 1024x1024, I think this is a recent requirement as of the new iPad intro) icon file shall be a PNG file.
Don't worry about what you see when extracting the file from a binary. The icon file can be uploaded through the browser and a PNG will just do fine.
