This may be related to #5405 (comment), try setting PDFJS.disableRange = true; and see if that helps.

Seems like setting PDFJS.disableRange = true; it's helps in iOS 10.0.1, but in iOS 10.1.0 can not load PDF file ,hasn't loading bar and exception tips , just black page.

@Snuffleupagus The problem still exist.
As I mentioned before, I tested in WeChat App in iPhone, NOT safari in iPhone.
Safari in iPhone is OK, but app in iPhone does NOT work.

@Snuffleupagus I have the same problem of @Lyife but in iOS 10.1.1.

I tried to set PDFJS.disableRange = true and changecheckRangeRequests in compatibility.js but I have a black page.

disable range request in iPhone

Better way but NOT necessarily best way to solve the IOS webview APP error: Unexpected server response (206) while retrieving PDF...

Details:
1. At the beginning, I only found the Error in IOS WeChat APP, so I solved it by checking WeChat:
9ad57d4

2. But I found this error in other IOS app, so I checked UA details of them as follow:

a) iPhone WeChat APP UserAgent (Fail):
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 MicroMessenger/6.3.30 NetType/WIFI Language/zh_CN

b) iPhone Other APP UserAgent (Fail):
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 QYZone

Maybe all webview app in IOS 10 have this problem, and since Safari & Chrome in IOS also does NOT support range request in IOS, so I think it's a better way to disable range request in iPhone by this regex:
var isIPhone = /iPhone/.test(navigator.userAgent);
if (isIPhone) {
    PDFJS.disableRange = true;
    PDFJS.disableStream = true;
}
