Additional Information
This is a known limitation. The crash is being observed on a 5+-year-old device with the lowest specification iOS device currently supported. The same survey with 1 million records in CSV used by pulldata does not crash on other iOS devices or Android devices with larger memory. Given the user requirement to have 1 million records in a CSV, the hardware used needs to be adequate to manage such a high volume of data. The error and crash are due to the device running out of memory, as the iPhone 6 and 6+ have a slower CPU and memory size compared to more current models. This issue can not be resolved by code changes in the app if trying to use 1 million records and searching through them using pulldata on the device.Workaround
The workaround is to use a better-suited device (iPhone 7 or above) with a faster CPU and a larger amount of available memory.
