mimeTyp that can't be recognise

[turk-jk]

Hi there,
I'm using Xcode 10.1
swift 4.2 tested on simulator, iphone and playground

when I init an UTI
let uti = UTI("com.apple.uikit.image") print(uti.declaration)

it prints // [:]

- Background of the problem

the reason I need this because when I copy an image from WhatsApp, WhatsApp will add one item that has three items in the
`let paste = UIPasteboard.general.item // type of [[String : Any]]

print (paste)

// [["public.png": <UIImage: 0x2821b5730>, {1024, 1017}, "public.jpeg": <UIImage: 0x2821e5c70>, {1024, 1017}, "com.apple.uikit.image": <OS_dispatch_data: data[0x2810a6c40] = { leaf, size = 1015803, buf = 0x11c6fc000 }>]]`

you can see WhatsApp add
[["public.png" "public.jpeg", "com.apple.uikit.image"]]

I always take only the first item of those three and their order changes sometimes, the problem occur when "com.apple.uikit.image" is the first item

thanks

@turk-jk Hi.

I could reproduce the behavior.

// Create UIImage
let renderer =  UIGraphicsImageRenderer(size: CGSize(width: 10, height: 10))
let image = renderer.image { _ in }

// Set image to pasteboard
let pasteboard = UIPasteboard.general
pasteboard.image = image

// Reproduced here
for item in pasteboard.items {
    let UTIs = item.keys.map(UTI.init)
    print(UTIs) // [public.png, public.jpeg, com.apple.uikit.image]
}

I think that com.apple.uikit.image is the UIKit internal UTI.

You should filter that.

let imageType = UTI(kUTTypeImage as String)
for item in pasteboard.items {
    // Filter by conformance
    let UTIs = item.keys.map(UTI.init).filter { imageType ~= $0 }
    print(UTIs) // [public.png, public.jpeg]
}

Great tip. I will try it Thanks.

I have just tested your code which works fine, but doesn't serve my app purpose well as it receive many different type of data not only kUTTypeImage
what I did is this

for item in pasteboard.items {
    print("item has keys \(item.keys)")
    let validItems = item.filter { UTI($0.key).filenameExtension != nil }
    print("validItems has keys \(item.keys)")
}

prints

item has keys ["com.apple.uikit.image", "public.png", "public.jpeg"]
validItems has keys ["public.png", "public.jpeg"]

Now I understand that I am relaying on the condition validUTI.filenameExtension != nil
would you have a better suggestion ?

thanks
