i've made an app with Filemaker ios SDK (18) and it works flawless.
I need to open this app from another one or from safari, and i'm using the custom url schema.
(i follow this tutorial to create the appdelegate)
https://github.com/starsite/SwiftFM/blob/master/FIAS-Swift-AppDelegate-walkthrough.md
The app opens, but i've got this error popup (when i open app form external url).
EDIT:
if i build a simply swift app, it works all well, it's probably a bug in FM sdk 18 (or something undocumented)
Looks like issue with URL. You have to make it in this view:
"fmp" should be changed on your own URL prefix.
fmp: //<user>:<pass>@<hostName>/<fileName> // user:pass
fmp: //<hostName>/<fileName>?script=<scriptName>¶m=<parameter> // parameter
fmp: //<hostName>/<fileName>?script=<scriptName>&variable=<variable> // variable
fmp: //~/<fileName> // an unopened file, from ~/Documents
fmp: //$/<fileName> // currently open file
