x/mobile: Info.plist not found for compiled xcframework

[Simon-Zeng]

Starting from XCode 15.3, each framework must have Info.plist located directly under framework root, otherwise app won't be able to run on Simulator (iOS device with iOS 17.4 or later?).
i.e. ProtonMail/gopenpgp#271

We don't have Info.plist file under gopenpgp.xcframework/ios-arm64_x86_64-simulator/Gopenpgp.framework/.

Could you please update procedure for "gomobile bind" to put an alias of Info.plist to framework root?
Thank you.

Anyone have a workaround for this? I can create the needed Info.plist in framework root, but it fails parsing. Not sure which keys are needed.

@scosman Could you please add possibility for users to pass parameter with an URL value of Info.plist?
Some thing like ./gomobile bind -target iOS -plist $PLIST_FILE_PATH

@Simon-Zeng I'm not a maintainer. Just trying to fix the same issue in my project, and get the info needed for the maintainers to make a quick fix. An alias won’t work as there are relative paths inside that top plist

I've found a working fix manually. I think we need this built into the go mobile framework generator. Slightly confusing since it involves 2 Info.plist files.

First one: the generated framework needs an Info.plist in each of the generated NAME.framework subfolders. This can just be an empty plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
</dict>
</plist>

Second one: the existing Info.plist that is generated in each nested framework folder, in the subpath Versions/Current/Resources/Info.plist

Looks like Xcode 15.3 is expecting 2 properties here: CFBundleExecutable (the name of the static library file), and CFBundleIdentifier (a bundle ID, I use the same string as the CFBundleExecutable).

Example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>CFBundleExecutable</key>
        <string>Appcore</string>
        <key>CFBundleIdentifier</key>
        <string>Appcore</string>
</dict>
</plist>

There is a 3rd Info.plist at the root of the xcframework. There's no need to change that.
