Hi,
Can someone point me to some documentation of Drag and Drop for iOS please?
I done loads of searches but can’t find a brief intro and some Sample Code.
I’ve not been working on iOS for some time and things seem to have changed
quite a lot.
Cheers
Dave
I read it (quickly) this morning and it seems quite well informed and well
written : https://www.hackingwithswift.com/whats-new-in-ios-11

Hi,
I should have said I’m using Objective-C not Swift and I’d much rather have
some written docs then a video for a number of reasons, the main one being I
have limited Internet access at the moment and I can’t find a way to download
the videos anymore…… Also, I find it takes much longer to ke
It’s right in the developer docs. In Xcode 9 open the doc viewer, flip open
UIKit in the outline on the left, then select Drag And Drop.

Hi,
I'm trying to validate an attribute of a NSManagedObject, I create a
transformable attribute called location, make it CLLocation, and define a
method on the object:
func validateLocation(_ value:
AutoreleasingUnsafeMutablePointer) throws {
if value.pointee == nil {

I don’t understand this. If you made the “location” attribute optional,
Thanks for quick reply.
I guess i should provide the full context, sorry I was unclear.
In my case, the location attribute is actually defined on a parent entity
(let's call it Parent), and it has two child entity (Child1 and Child2), I want
location to be optional for Child1 but not for Child2

You're the hero man!
I totally forgot about the @objc case in swift 4. After prefixing it to my
validation method, it works!
And if you don't mind me asking, what do you use instead of Core Data? It's
indeed not that friendly to swift (relationships being NSSet instead of
Set etc). Also I don'
