IB Designables Error

[alanshih]

I am using xCode 8 with Swift 2.3 so I install TextFieldEffects using Cocoapods
pod 'TextFieldEffects', '~> 1.2.0'

The problem is that I get errors ever since I upgraded to xCode 8

I believe it's because of the @IBDesignable notation for the TextFieldEffects as it is only throwing errors on views with these custom TextFields.

Hi,

Can you confirm this is due to this library? A sample project would be awesome for testing this

[datamaru]

I also encountered this problem but it also occurred when I was using another library that use IBDesignable so I guess the problem is in the XCode itself. I suggest you use XCode 7.3 if you are still developing with Swift 2.3 like me.

I have attached the error:
Application Specific Information:

CoreSimulator 303.8 - Device: IBSimDeviceTypeiPad2x - Runtime: iOS 10.0 (14A345) - DeviceType: IBSimDeviceTypeiPad2x

Also, the custom TextFields use to render properly, but now they look strange on the Storyboard.

@datamaru My computer automatically upgraded me to XCode 8. I don't suppose there is a way to downgrade?

[datamaru]

You can download XCode 7.3.dmg at the Apple Developer Download section. Go here https://developer.apple.com/download/ and scroll all the way down to found "See more downloads" button. You can found Xcode 7.3 there.

@raulriera
Debuged the Yoshiko I am using and it is failing on:

private var placeholderHeight : CGFloat {
        return placeHolderInsets.y + placeholderFontFromFontAndPercentageOfOriginalSize(font: font!, percentageOfOriginalSize: placeholderFontScale).lineHeight
    }

EXC BAD ACCESS

[raulriera]

Can you provide a sample project? this error doesn't happen on the Sample project in this library

[Nallo]

In my project I get the same error as the one of alanshih. I am using Pods which do not have any @IBDesignable.

Trying with an empty workspace after getting TextFieldEffects using Pod Install the error does not show up.

I am guessing, if we import TextFieldEffects with drag/drop the issue should go away (Not tested yet).

[alanshih]

@Nallo Do you know of a way to fix it on existing projects that is using pods?

[Nallo]

@alanshih I removed from the source of the Pod the string @IBDesignable.

In my project I am using only HoshiTextField therefore, I looked for the HoshiTextField.swift file and I changed the first line of the class from @IBDesignable public class HoshiTextField: TextFieldEffects { to public class HoshiTextField: TextFieldEffects {.
If you are using other custom textfields you should do the same procedure for each textfield class. After that, clean your project, restart Xcode and perform a full build. The errors should be gone but you won't be able to see anymore the UI updates of the textfields in the Storyboard.

[alanshih]

@Nallo That did it :). Thank you. Is this considered a xCode bug that will eventually be fixed one day? I don't really understand the issue.

[Nallo]

@alanshih I have no idea whether is a bug in Xcode or in the Pod management. However, you can stay updated by checking this repo updates.

Hope this helps.

[alanshih]

@Nallo actually, pulling out the IBDesignable did not fully solve the issue. If I add a new "YoshikoTextField" after removing the @IBDesignable, it will not render and throw the same error.

The only workaround I have found is to copy and paste a working custom TextField into the view

[Nallo]

@alanshih my solution was only a workaround for my specific case.

If you add a YoshikoTextField and you get the error, you need to remove the @IBDesignable string from the YoshikoTextField.swift file, clean the project, close Xcode and reopen Xcode again.

Yeah, I really wanted to use this library but it just isn't playing nice in my storyboard and the attributes aren't displaying properly when I try to adjust settings/properties. Better documentation would have been nice.

[raulriera]

Anythign ni particular Nathan? All files hace documentation headers on them. Also, PRs are always welcomed.

[StephanKonig]

When using TextFieldEffects in Xcode 9, it tells me "Designables: Build failed".

[raulriera]

Can you provide more info? What version, how did you install it, does it happen in the sample project, etc?

[StephanKonig]

I found out that it is a bug in Xcode 9, not in the code...

Hello,

I am currently experiencing the same problem.
I installed this package by Cocoapods.

I implemented "KeadeTextField" on a storyboard, in recent days it worked properly !

Since the launch of my project today, this problem has appeared during the build.
When I remove the classes from my TextField this problem disappears.

As soon as I add one of the classes, the problem reappears.

"@IBDesignables" always appears as "Updating".
I tried to add "@IBDesignables" by hand and it appears as "up to date" but the problem is the same.

Package version : TextFieldEffects (1.4.0)
XCode Version 9.3

I hope this will help you !
