Why does the debugger 'po' works with var:
var myDict = currentImageDownloader.dict
As shown here:
(lldb) po myDict
Some
{
[0] = {
key = "ispublic"
value = (instance_type = Builtin.RawPointer = 0xb000000000000013)
(lldb) po myDict
error: <EXPR>:1:1: error: use of unresolved identifier 'myDict'
myDict
...
yet via 'let':
let myDict = currentImageDownloader.dict
The debugger 'po' doesn't work:
(lldb) po myDict
error: <EXPR>:1:1: error: use of unresolved identifier 'myDict'
myDict
^
Although I can view everything via 'let' or 'var' using the debugger's frame command:
(lldb) fr v
(UICollectionView) collectionView = 0x00007fc2d2821600 {
UIKit.UIScrollView = {
UIKit.UIView = {
UIKit.UIResponder = {
ObjectiveC.NSObject = {}
}
}
}
}
(NSIndexPath) indexPath = 0xc000000000000016 {
ObjectiveC.NSObject = {}
}
(FlickrSwift.ViewController) self = 0x00007fc2d2580f20 {
UIKit.UIViewController = {
UIKit.UIResponder = {
ObjectiveC.NSObject = {}
}
}
collectionView = Some
}
(FlickrSwift.ImageDownloader) currentImageDownloader = 0x00007fc2d4449750 {

bigImage = nil
dict = Some {

}

}
[3] = {

(AnyObject) cell = <variable not available>
(UIImageView) photoImageView = <variable not available>
(UIImage) image = <variable not available>
