Hello friends.
O swit 2.x I use the below code and worked ok, but I was trying use on swift 3 and I cant, I dont understand how to write it on swift 3

//do something

Hello friends.
O swit 2.x I use the below code and worked ok, but I was trying use on swift 3 and I cant, I dont understand how to write it on swift 3
dispatch_async(dispatch_get_main_queue()) {
//do something
}
How can I write this code on Swift 3?
DispatchQueue.main.async {
// do something
}
DispatchQueue.main.async {
// do something
}
I could not understand, but it does not work. I try to Execute:
DispatchQueue.main.async {
self.refreshControl.beginRefreshing()
}
But it does not work.
Also
dispatch_async(dispatch_get_main_queue(), {
self.refreshControl.beginRefreshing()
}
in Swift 2 work perfect.
Try the following:
DispatchQueue.main.async(execute: {
/// code goes here
})
DispatchQueue.main.async(execute: {
self.refreshControl.beginRefreshing()
})
It still do not work 😟
Does it not execute, or do you get an error?
1) No Errors
2) Code executed (I add some print("test") inside), but I think NOT in main thread, because I do not see any changes in GUI
… but I think NOT in main thread …
Add code like this to your block:
assert(Thread.isMainThread)
That’ll trap if you’re off the main thread. Conversely, if it doesn’t trap then you know the problem is something else.
Share and Enjoy

Thank you so much. I found a problem.
It happens, because I executed:
self.refreshControl.beginRefreshing()
twice. After I removed the second execution everything start works perfect. Also in Swift 2 it works without any problem.
