Retrieving data

[gmcusaro]

How is it possible with this code in READ.me to recover name, version, profile type, copyright, etc ...?

for tag in file.tags {
  print(tag) 
}

Something like that is possible?

Have you seen the code sample in the readme?

let file = try ICCColorProfile(data: data)
for tag in file.tags {
    print(tag)
}

What you can do to create an interface like the above is switch on tag and do different things based on the tag.

Would it be useful for you to get the textual signature of the tag or data type for each tag?

I saw your code, you did a great job following the pdf specs.
I am attaching the console output for sRGB.icc for example.
Not necessarily a window, but if you want to add something similar in SwiftUI it would be very useful.
A code example to get more readable tags like: profile name, version, colorSpace, intent, copyright, acsp signature, etc...

Something like that:

version: '2.0',
intent: 'Perceptual',
deviceClass: 'Monitor',
colorSpace: 'RGB',
connectionSpace: 'XYZ',
description: 'sRGB IEC61966-2-1',
deviceModelDescription: 'IEC 61966-2-1 Default RGB Colour Space - sRGB',
viewingConditionsDescription: 'Reference Viewing Condition in IEC 61966-2-1',
copyright: 'Copyright International Color Consortium'

Going deeper than the example code in description, how to get TagTypeSignature enum cases?

            let myData = try Data(contentsOf: url)
            let profile = try ICCColorProfile(data: myData)
            for tag in profile.tags {
                switch tag {
                    case .profileDescription(.textDescription(let signature)): print(signature.sig)
                    default: break
                }
            }

I think I’m going to have to make some breaking changes and have something like

struct ICCRecord
{
public let signature: String
public let dataType: String
public let data: ICCRecordData
}

where data is a enum of different types

[gmcusaro]

With signature I refer to an enum

public struct textDescriptionType {
    public let sig: TagTypeSignature // <-- this enum
...

Is possible and how retrieve the data of public enum TagTypeSignature: String?

public enum TagTypeSignature: String {
    /// [ICC.1:2010] 10.2 chromaticityType
    case chromacityType = "chrm"
    
    /// [ICC.1:2010] 10.3 colorantOrderType
    case colorantOrderType = "clro"
    
    /// [ICC.1:2010] 10.4 colorantTableType
    case colorantTableType = "clrt"

    /// [ICC.1:2001-04] 6.5.15 screeningType
    case screeningType = "scrn"
...

See #2

I'm not going to create a UI to display things, as it should be trivial to do that in your own SwiftUI component once that PR is merged in (please review and let me know so I can submit:) )

If you do create the component and want to send it in as a PR I may consider it

[gmcusaro]

This refactoring makes everything much more practical. Grate job! I agree with you, the interface becomes a trivial thing with these changes. Everything looks ok, for merging the PR!
In the new sample code print (tag.Signature), signature has a lowercase s.

Well noticed, find replace is annoying in xcode :( Fixed

Also released 1.1.0 - update!
