Thanks Brian, so I run your version downloaded from here, and break point on viewDidLoad and your stack trace is: run application: 0 HomeController.viewDidLoad() 21 UIApplication 22 Main 23 Start 24 Start print self.table from numberOfRowsInSection Optional(; layer = ; contentOffset: {0, -88}; contentSize: {0, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x600001c6d620>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {0, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x600001c6d620>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {375, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x600001c6d620>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {375, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x600001c6d620>>) Now if I create a post, viewDidLoad doesn't fire, but the post updates and the output is: Optional(; layer = ; contentOffset: {0, -88}; contentSize: {375, 9972.6666666666642}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x600001c6d620>>) So same pointer address, makes sense. Run application: stack trace is the same, with the output: Optional(; layer = ; contentOffset: {0, -88}; contentSize: {0, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x6000014961f0>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {0, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x6000014961f0>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {375, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x6000014961f0>>) Optional(; layer = ; contentOffset: {0, -88}; contentSize: {375, 0}; adjustedContentInset: {88, 0, 83, 0}; dataSource: <_UIFilteredDataSource: 0x6000014961f0>>) now when I create a post, my viewDidLoad IS fired, with a stack trace of: 0 HomeController.viewDidLoad() 5 [UITableViewController TableView] 6 closure #1 in HomeController.fetchPosts() 7 closure #1 in Service.fetchPosts(completion:) 8 closure #1 in closure #1 in DataRequest.response(queue:responseSerializer:completionHandler:) 17 UIApplicationMain 18 main 19 start Enqued from (Thread 19) 0 dispatch_async 1 OS_dispatch_queue.async(group:qos:flags:execute:) () 2 closure #1 in DataRequest.response (queue:responseSerializer:completionHandler:) Any ideas on that stack trace, where it's coming from? Thanks
