iOS Swift判断代码运行在模拟器上

iOS模拟器有些功能没有，比如拍照，因此代码中需要加个模拟器判断，查了好多文章，终于找到了。swift代码如下：

struct Platform {    static let isSimulator: Bool = {        var isSim = false        #if arch(i386) || arch(x86_64)            isSim = true        #endif        return isSim    }()}// Elsewhere...if Platform.isSimulator {    // Do one thing}else {    // Do the other}
