问题：

iOS12.2以下的系统会崩溃，运行报错：

dyld: Library not loaded: /usr/lib/swift/libswiftCoreGraphics.dylib

解决：

Xcode14.0会报错，14.1以上版本已修复，如果使用的是Xcode14.0则进行以下设置：
如果是工程报错，
在build phase -> Link Binary With Libraries中添加libswiftCoreGraphics.dylib
或者
在Build Settings -> OtherLinkFlags 添加： -Wl,-weak-lswiftCoreGraphics

如果是pod引入的库报错，
在pod中找到对应的target -> General -> Link Binary With Libraries中添加：libswiftCoreGraphics.tbd
或者
Build Settings -> OtherLinkFlags 添加： -Wl,-weak-lswiftCoreGraphics
或者
将库改成手动引入。

问题：

部分SDK pod下来后需要指定证书签名，默认为none，会导致编译失败

解决：

在Podfile文件中添加以下方法，二选一，然后终端执行pod install

#解决方案1
post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
           config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
           config.build_settings['CODE_SIGNING_REQUIRED'] = 'NO'
         end
    end
  end
end

#解决方案2
post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings["DEVELOPMENT_TEAM"] = "Your Team ID"
         end
    end
  end
end

问题：

项目无法运行到iOS16设备上，无法选中设备，提示developer mode disable.

解决：

手机升级到iOS16后，设置中多了开发者管理开关，默认是关闭的，前往设置->隐私与安全性->开发者模式，点击开启即可，如还不行，则重启手机。

问题：

横竖屏切换失败

解决：

if (@available(iOS 16.0, *)) {
    
    [vc setNeedsUpdateOfSupportedInterfaceOrientations];
    
    UIWindowScene *windowScene = (UIWindowScene *)[[[UIApplication sharedApplication] connectedScenes] allObjects].firstObject;
    
    UIWindowSceneGeometryPreferencesIOS *perference = [[UIWindowSceneGeometryPreferencesIOS alloc] init];
    
    perference.interfaceOrientations = UIInterfaceOrientationMaskLandscapeRight;
    
    [windowScene requestGeometryUpdateWithPreferences:perference errorHandler:^(NSError * _Nonnull error) {
        
        RjLog(@"强制%@错误:%@", isLaunchScreen ? @"横屏" : @"竖屏", error);
        [AnalyticsHelper logEventWithName:@"ChangeOrientationFailed"];
        
    }];
    
}

以下是使用Xcode14以下版本的写法：

if (@available(iOS 16.0, *)) {
    void (^errorHandler)(NSError *error) = ^(NSError *error) {
        RjLog(@"强制%@错误:%@", isLaunchScreen ? @"横屏" : @"竖屏", error);
        [AnalyticsHelper logEventWithName:@"ChangeOrientationFailed"];
    };
    
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
    
    SEL supportedInterfaceSelector = NSSelectorFromString(@"setNeedsUpdateOfSupportedInterfaceOrientations");
    [vc performSelector:supportedInterfaceSelector];
    
    NSArray *array = [[UIApplication sharedApplication].connectedScenes allObjects];
    
    UIWindowScene *scene = (UIWindowScene *)[array firstObject];
    
    Class UIWindowSceneGeometryPreferencesIOS = NSClassFromString(@"UIWindowSceneGeometryPreferencesIOS");
    
    if (UIWindowSceneGeometryPreferencesIOS) {
        
        SEL initWithInterfaceOrientationsSelector = NSSelectorFromString(@"initWithInterfaceOrientations:");
        
        UIInterfaceOrientationMask orientation = UIInterfaceOrientationMaskLandscapeRight;
        //
        id geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] performSelector:initWithInterfaceOrientationsSelector withObject:@(orientation)];
        
        if (geometryPreferences) {
            
            SEL requestGeometryUpdateWithPreferencesSelector = NSSelectorFromString(@"requestGeometryUpdateWithPreferences:errorHandler:");
            
            if ([scene respondsToSelector:requestGeometryUpdateWithPreferencesSelector]) {
                [scene performSelector:requestGeometryUpdateWithPreferencesSelector withObject:geometryPreferences withObject:errorHandler];
            }
        }
    }
#pragma clang diagnostic pop
    
}

问题：

新建项目执行pod init 报错：

***:in `force_encoding': can't modify frozen String: "[Xcodeproj] Unknown object version (56)." (FrozenError)

解决：

将Project format的值从Xcode 14.0-compatible改为Xcode 13.0-compatible即可
