Parse-sdk-ios-osx: Xcode 12 beta 4 fails to build project with SDK

[bmueller]

I'm getting an error when trying to build a project on the newly-released Xcode 12 beta 4:

Incompatible block pointer types sending 'void (^)(ParseClientConfiguration *__strong)' to parameter of type 'void (^ _Nonnull)(id _Nonnull __strong)'

The error doesn't happen with beta 3 or earlier. I have the SDK integrated via CocoaPods.

I can confirm this issue.

clang got a bit stricter in checking for qualified id block parameters I guess: https://github.com/llvm/llvm-project/commit/73152a2ec20766ac45673a129bf1f5fc97ca9bbe

The error occurs at this line:
https://github.com/parse-community/Parse-SDK-iOS-OSX/blob/1ede703d5119a6a673e2654195e87c7f7f82ecf6/Parse/Parse/ParseClientConfiguration.m#L129

One possible solution could be to not use the -[ParseClientConfiguration configurationWithBlock:] in copyWithZone.
For example:

- (instancetype)copyWithZone:(NSZone *)zone {
    ParseClientConfiguration *const configuration = [[ParseClientConfiguration alloc] initEmpty];
    if (!configuration) return nil;
    // Use direct assignment to skip over all of the assertions that may fail if we're not fully initialized yet.
    configuration->_applicationId = [self->_applicationId copy];
    configuration->_clientKey = [self->_clientKey copy];
    configuration->_server = [self.server copy];
    configuration->_fileUploadController = self->_fileUploadController;
    configuration->_localDatastoreEnabled = self->_localDatastoreEnabled;
    configuration->_applicationGroupIdentifier = [self->_applicationGroupIdentifier copy];
    configuration->_containingApplicationBundleIdentifier = [self->_containingApplicationBundleIdentifier copy];
    configuration->_networkRetryAttempts = self->_networkRetryAttempts;
    configuration->_URLSessionConfiguration = self->_URLSessionConfiguration;
    return configuration;
}

Will this be fixed on CocoaPods anytime soon or will we have to use our own build?

[novemTeam]

I have the same issue. I can't run my app anymore. Waiting for a fix soon

[JoeSzymanski]

This issue is blocking us currently. Is there any timeframe for when a fix will be merged and publicly released?

[drdaz]

@JoeSzymanski I just merged @HeEAaD's PR to this fix. So assuming our tests pass, you should be good with current master. Not sure on the timeframe for a release. ASAP.

[JoeSzymanski]

@drdaz Thanks for the quick update. We can likely make use of master directly, though obviously a full public release would be better if we can manage it

[bcbeta]

I'm still getting this error on the master branch?

[funkenstrahlen]

I can confirm the fix on master fixes the build issue on Xcode 12 beta 4.

@bcbeta Please double check if you actually use the code on master in your project.

I am using
pod 'Parse', :git => 'https://github.com/parse-community/Parse-SDK-iOS-OSX.git', :branch => 'master'
and I ran pod repo update but it is still not pulling in the change. Must be a problem on my end.

[bcbeta]

Any idea why I am not getting the most recent master update? Sign in with Apple isn't there either. Here is my podfile-

`platform :ios, '12.0'
use_modular_headers!

def parse_utilities
pod 'Parse/UI', :git => 'https://github.com/parse-community/Parse-SDK-iOS-OSX.git', :branch => 'master'
pod 'Parse/FacebookUtils', :git => 'https://github.com/parse-community/Parse-SDK-iOS-OSX.git', :branch => 'master'
end

def parse_framework
pod 'Parse', :git => 'https://github.com/parse-community/Parse-SDK-iOS-OSX.git', :branch => 'master'
end

target 'BackcountrySkiTracker' do
parse_framework
parse_utilities
pod 'INTULocationManager'
pod 'DKImagePickerController'
pod 'UIImageView-Letters'
end

target 'BCWeatherWidgetExtension' do
parse_framework

end
`

For reference above query has been posted on Stack Overflow.

After deintegrating and reinstalling about two dozen times, I was finally able to pull from the master 🤷🏻‍♂️

[bmueller]

When I use the master branch, I get an error in ParseModule.h saying "Module Bolts not found". When I switch between the release and master branches, it looks like "@import Bolts" was added to the top of this file. Anyone else having this issue or know how to fix?

[TomWFox]

Btw 1.19.0 has now been published to Cocoapods with the fix for this issue.
