在 ZA5084C5B36F309E58B2629BED5212E6 项目中的 Swift 文件中使用 Objective-C Singleton

Question

I've got my project written in Objective-C . I am learning about bridging.

I bridged successfully Swift into my Objective-C project. I did some VC pushing between Objective-C VC and Swift VC . Everything works as it supposed to.

However, I created the reference to my Objective-C NetworkManager (I used Singleton pattern) in my Swift file like that:

let networkManager = NetworkManager.sharedManager()

For some reason I cannot use methods from it.

networkManager.getUserInfo() // .getUserInfo() will not appear!

Just to show you how I've created my NetworkManager as a Singleton. I found that solution online and it was quite old, if you have any better solution, I would be more than happy to get some insight:

+ (id)sharedManager {
    static NetworkManager *sharedMyManager = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        sharedMyManager = [[self alloc] init];
    });
    return sharedMyManager;
}

-(id)init {
    if (self = [super init]) {
        someProperty = @"Default Property Value";
        self.cache = [[NSCache alloc] init];
    }
    return self;
}

Not sure what is the issue here. Thank you all for the help.

For those who may look for the answer in the future.

I've been advised to not use id type when bridging with Swift. I've changed:

+ (id)sharedManager {

to

+ (NetworkManager *)sharedManager

And now everything works fine.
