I am trying to figure out how to use OpenGL in Xcode five but I cannot figure it out. Is there a relatively good tutorial out there to help with this? I am not looking for the best opinions. I am just looking for a list of some that might help. I have found a couple but they seem to be outdated. Thanks.
This link will give you a basic tutorial in how to get started on OpenGLES 2.0 on iOS.
It goes over the basic principles of vertex and fragment shaders. It also goes through the creation of objects, and some basic animations.

I new to iOS development. I working on CIFilters and I want to make custom filter using metal framework in iOS.
But I couldn't find any beginner level resources that could help me to understand the process step by step.
Is there any book/video tutorials or something that teaches Metal ?
Here you will find apple documentation, sample code, and videos. link
This website is will help you to understand metal: link

Sorry I am pretty inexperienced with ARKit. I am working on an app and it will have more features later but the first step would basically be recreating the measure app that is included with iOS. I have looked at the documentation that Apple gives and most of it is for stuff like face tracking, object detection, or image tracking. I wasn't sure exactly where to start. The rest of the existing code I have now is written in SwiftUI if that matters. Thank you!
Understand that it can be quite confusing in the beginning. I would recommend to walk throught the toruial at raywenderlich.com. This toturial from Codestars on Youtube is also very good if you like to listen and watch instead of reading. Both talks go throught a lot of important parts of ARKit so I really recomend it. After that you problably have a create understanding and you clould watch Apples WWDC2019 talk What's new in ARKit 3.
Hope I understood your question correctly and please reach out if you have any questions or other concerns.
I've been looking at a lot of tutorials trying to find a way to make an OpenGL app written in Swift, but I can't seem to find a good template to use.
Most tutorials suggest using a blank one, but then I have to write a ton of files (such as AppDelegate) all from scratch, which I have no clue how to do.
I tried all the links on this, but the first one doesn't even work and the second one is in Objective-C.
Anyone have anything that might help me?
I ended up figuring it out myself by using GLKit and smashing together old tutorials. Since OpenGL is just a bunch of functions, all you really need to do is find the right parameters for your programming language.
For anyone else trying to do this, there's some fairly useful resources here and here, and it's also useful to shove in some ported code from Ray Wenderlich if you get stuck. Good luck!
I’m new for OpenGL ES 2.x on iOS, and I’m trying to render some characters in the OpenGL ES 2.x scene. But I don’t know how to do it.
So anyone who can point me in the direction of an Objective-C tutorial or post some sample code?
Any help or advice would be much appreciated.
This question is asked a lot because OpenGL does not have built-in support for text fonts. There is a good survey of solutions and discussion here:
http://www.opengl.org/archives/resources/features/fontsurvey/
http://stackoverflow.com/questions/18557535/text-font-rendering-in-opengles-2-ios-coretext-options-and-best-practice
But the easiest solution by far is to use the Print3D class in the PowerVR SDK:

I've hired a developer to work on an iPhone & iPad application and as part of the application we would like to have a particle effect.
How do you implement particle effects by using CoreGraphics?
Please note that I've referred the developer to the following link, but he's told me it doesn't work well due to leaks:
http://www.clingmarks.com/generate-particles-along-a-path/822
If I may suggest this: http://www.raywenderlich.com/6063/uikit-particle-systems-in-ios-5-tutorial tutorial in an attempt to implement your particles, maybe you will have some better luck with it. I havent personally used it, but I've used tons of other tutorials from Ray's site, and all of them are fantastic.
Additionally, if you just want to debug your current implementation, this one seems to be up your alley: http://www.raywenderlich.com/2696/how-to-debug-memory-leaks-with-xcode-and-instruments-tutorial.
Hope that helps!
