Ambiguous use of DispatchQueue on trying to use main thread
提问by Jonathan Bursztyn
This is a weird issue and I can't seem to find any help. On Swift 3, trying to make a call on the main thread I try to use DispatchQueue.main.async, but it doesn't compile.

Try this code instead, this is the Swift 3.0 syntax:
试试这个代码，这是 Swift 3.0 语法：
DispatchQueue.main.async(execute: { () -> Void in
})
For Swift 4.x you can also use:
对于 Swift 4.x，您还可以使用：
DispatchQueue.main.async {
}
