SwiftUI List performance

Our studio was developing a slot project in Cocos2d using Spritebuilder, however with the latest features available in Sprite-Kit we have decided to convert this ongoing project to Sprite-Kit.We are experiencing some performance issues with deep scene graphs where the CPU usage seems to escalate and cause a drop in frames. At first I thought it was something in our code but I was able to recreate the problem starting from a blank Sprite-Kit template project. I have added a link to the sample project.Sample Project Link: https://dl.dropboxusercontent.com/u/966509/test2.zipMy scene graph is as follows and uses reference nodes to create the scene graph depth:GameScene -> GameView -> SlotView -> Reel -> TileContainer -> Tile. I should note that there are 5 reels in the scene and each reel contains 5 tiles. This totals out at around 50-60 nodes at a depth of about 6 in the tree graph. I believe most of the nodes are skspritenodes. My actual project has a deeper tree graph and the performance

ok, I am kinda new to app development. and what i am confused about is how do developers get images/graphics/photos etc for their app. Say, I am making a recording APP and i want a Microphone image (Drawn/animated, not real microphone) so How do i do it? is there an app in Macstore that lets you create a picture? Till now i have always used contents on the web that are listed as Free for commercial use, but i want my own now? Do i have to learn or buy Photoshop for this? basically how do i get files for image assets?

My application presents a list of words to the user, who will then select a number of them. They may also edit the words in the table. The table is a single column, cell-based table.The application is very small, so the app delegate is being used as the NSTableViewDataSource and NSTableViewDelegate. The data source is working correctly, as the right words are appearing in the table. I am able to get a list of selected words from the table after the user presses the Done button.The part that is missing is getting edits of words in the table. I have added the - (void)tableView:setObjectValue:forTableColumn:row: method, right next to the methods for populating the table. I put a call to NSLog in the method, but the method is not being called- nothing appears in the console.What might prevent the method from being called? Exactly what user actions will trigger the sending of the message to the table data source?ThanksAndrew

Hello to everyone.I searched for this on the forums bur nothing useful came up, so i will ask this out.My situation is as follows, i'm working for an school and i've developed 3 applications, one for students, one for parents and one for teachers, the student's app is published on the app store, but, due to security and secrecy matters with the information managed on the parents and teacher app (the parents app is a direct link between the school and the parents, where they get exclusive information from their son or daughter) the parent's app and the teacher's app will not be published on the appstore.My questions are, is there a way to restrict who download the app on the appstore? or there is a way to release an app approved by apple without publishing it on the app store? using the adhoc provision profile is out of the question because there are more than 500 students.)i mean don't get me wrong, i want to publish the apps to the appstore because it will means it passed all the filters to get in shape, but

Hello everyone!I'm just curious about how to go about attaching a button to an action or segue that would dismiss all views except for the first one. I don't want to just add another connection because then it is just messing with the view hierarchy. I want to try and make this process as power and performance efficient as possible.Thanks!🙂

I see my develop program membership has been merged into one. But what is Device Reset Date listed under the membership section?
